Real Designs was a Southern California company that produced nice chainrings and decent hubs.

The front hubs didn't have any noteworthy problems -- mine I bought used and it spun true under my 200+ pounds for over four years of regular use. I wouldn't hesitate to run one again, except that I'm leaning towards through-axles for any new construction projects.

The rear hubs had some issues, but there are a few items that come up in a quick Google search explaining some home-spun remedies to install a spacer to solve the issue of excess play. Not ideal, but for the right price...

So front = good, rear = problematic but workable if you've got the inclination.
